Description:
------------
Built with afl-clang-fast and ASan/UBSan on Fedora 26 x64. While fuzzing with AFL this stack-overflow was triggered after multiple runtime errors.

Test script:
---------------
<?php
function test(){}function gen(){foreach(0as$t){yield;}test(...gen());}test(...gen());[

Expected result:
----------------
The opposite of whatever is happening here. 

Actual result:
--------------

Breaking news: 9 out of 10 fuzzers don't know what infinite recursion is.

Not sure about the "runtime errors", since they seem to be happening all over the codebase.

This is a standard infinite recursion stack overflow. Marking this as a duplicate of bug #64196 (which is for __clone()), as these are all the same really.
